An isometric exercise is an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words isos (equal) and -metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction ...
Chapman's physical exerciser. A second device, invented in 1937 by Arthur William Chapman would be used to create the Bullworker.. The patent states: The invention relates to physical exercisers for human use, and seeks to provide in a single device means whereby a large variety of beneficial exercises for the body and limbs may be carried out.
The most common plank is the forearm plank which is held in a push-up-like position, with the body's weight borne on forearms, elbows, and toes.Many variations exist such as the side plank and the reverse plank.
An isometric exercise device is a device used to exercise most body parts including the wrist and is often used as part of physical therapy or in order to build muscle strength in a low impact manner. Devices can range in size from large bulky machines used by physicians to small hand-held devices that can be used by an individual.

Soreness can theoretically be avoided by limiting exercise to concentric and isometric contractions, [11]: 112 but eccentric contractions in some muscles are normally unavoidable during exercise, especially when muscles are fatigued.
This type is typical of most exercise. The external force on the muscle is less than the force the muscle is generating - a shortening contraction. The effect is not visible during the classic biceps curl, which is in fact auxotonic because the resistance (torque due to the weight being lifted) does not remain the same through the exercise.
